BallRod Mills have heavy rolled steel plate shells which are arc welded inside and outside to the steel heads or to rolled steel flanges, depending upon the type of mill. The double welding not only gives increased structural strength, but eliminates any possibility of leakage.

Grinding media steel balls are used for ball mills and are made of hardened steel. Used hardened steel media balls can be reused if in good condition. Our ball milling media for sale can be supplied to your location anywhere in the world.

The operating principle of the ball mill The operating principle of the ball mill consists of following steps. In a continuously operating ball mill, feed material fed through the central hole one of the caps into the drum and moves therealong, being exposed by grinding media.

While all Ball Mill bushings are scraped in the shop to fit either a jig mandrel or the head proper to which it is to be fitted, nevertheless there is a certain amount of seasoning and dimensional change which goes on in the type of metals used. Therefore if high spots are found, the mill should be raised, the bushings removed and rescraped. Bluing may be used to assist in detecting high spots.

At the short ball mill grinding is a more rough and for grinding fineness a lot of material has to be returned from classifier to the mill, it leads to mill overload. In long ball mills the grinding occurs only at the front and the rest of the balls in the drum only increases power consumption.

In ball milling of dry solids the main independent variables are mill diameter, mill speed, media size, solids loading and residence time. For most companies the production mill already exists so we can ignore mill diameter and focus on the other variables.

The balls are of the cast semisteel type, typical of those used in the South African gold mining industry. These balls suffer from porosity, the result of core shrinkage during rapid cooling in the mould. The porosity is not central due to uneven cooling of the balls. When the ball is worn to the point where the porosity is exposed, it wears very rapidly into the porous section to form a bowl ...
